Problems solved by technology

In the traditional teaching mode, not only the workload of teachers is heavy, but also it is difficult to form an objective and fair performance evaluation
In addition, due to the closedness of the manufacturer's group experiment unit, students cannot touch the software and hardware inside the equipment, and the experiment often stays at the level of process operation and principle verification
Due to the above problems, students know the process of microcomputer relay protection, but it is difficult to know why, so the enthusiasm for the experiment is not high

Abstract

The invention discloses a network type microcomputer relay protection experiment system and method, wherein the experiment system comprises N microcomputer relay protection devices, N simulation execution devices, a microcomputer relay protection tester, and a teacher-side computer which is provided with an experiment management program. One microcomputer relay protection device and one simulationexecution device are in bidirectional connection to form a group of experiment units for a group of experiment teams to carry out experiments, and the N groups of experiment units form a network typeexperiment system. The teacher-side computer is remotely connected with the microcomputer relay protection tester, the output end of the microcomputer relay protection tester is connected with the microcomputer relay protection device in each group of experiment units, and the microcomputer relay protection device in each group of experiment units is also connected with the teacher-side computer;the experiment system comprises N groups of same experiment units for N experiment teams to simultaneously carry out experiments on the same experiment project so as to achieve the purpose of competition of different experiment teams.

Description

technical field [0001] The invention relates to the technical field of power system protection simulation teaching, in particular to a network type microcomputer relay protection experiment system and method. Background technique [0002] Power system relay protection means that when a fault or abnormal operation occurs in the power system, the fault signal is collected and the fault type and fault point are automatically identified, and a trip command is issued to quickly remove the fault, eliminate abnormal conditions and give an alarm. The first line of defense for safe and stable operation. The basic requirements of power system for relay protection are quick action, selectivity, sensitivity and reliability. [0003] Power system relay protection has realized the transformation from traditional physical relay combined protection mode to microcomputer protection mode, presenting a digital trend. Microcomputer protection adopts the operation logic of software program to ...
